”There are no known clinical side effects specifically arising from the use of hyperflexion. However, there are serious concerns for a horse’s well-being if the technique is not practiced correctly. The FEI condemns hyperflexion in any equestrian sport as an example of mental abuse. The FEI states that it does not support the practice.”

(Veterinärkommittén 10 april 2008)

FEI:s definition av hyperflexion, eller rollkur:
”Hyperflexion of the neck is a technique of
working/training to provide a degree of longitudinal flexion of the mid-region of the neck that
cannot be self-maintained by the horse for a prolonged time without welfare implications.”
